I have a warranty for a set of tires,every time I go in to have them rotated/balanced they offer they're "suggested services" which I don't need because I do all the required maintenance on my car except tires.Well saying no is all it takes for them to act like Spoiled Teenage Girls.The front drivers side tire has a leak and they told me"since we can't find what's wrong with it we can't replace it"Apparently a warranty doesn't cover incompetence via the employees.If you can't Honor a warranty then maybe it's not the field of work for you.
